I Specification of Letters Patent.

Patented Jan. 1, 1907.

Application filed October 12,1906. Serial rt. 338,576. I v

To (tZZ whom it may concern: Be it known that I, NEIL McINNEs, a citizenof the United States of America, residing at Allegheny, in the county ofAllegheny and State of Pennsylvania, have invented certain new anduseful Improvements in Pressed- Steel Connecting-Bars, of which thefollowmg 1s a specification, reference being had therein to theaccompanying drawings.

This invention relates to pressed-steel connecting-bars adapted for useas car-truck levers, connections for the, sivitch points ofrailway-switches, and for other purposes.

The primary objectof the invention is to provide a pressed-steelconnection of light but strong and durable construction capable of beingmanufactured at small expense of labor and material.

The construction of the improvement will be fully described hereinafterin connection with the accompanying drawings, which form a part of thisspecification, and its novel features will be defined in the appendedclaims.

In thedrawings, Figure l is a top planview ofa blank from which theimproved connec- ,tion'is made. Fig. 2 is a side elevation of aconnection constructed in accordance with the same. Fig.

the invention. Fig. 3 is a top plan view of 4 is an end view thereof.Big. 5 is a transverse section 011 the line :20 :1: of Fig. 2, and Fi 6is a similar section illustrating a mod'ifie construction.

The reference-numeral 1 designates a blank comprising a flat steelplate, longitudinally slotted and perforated at its ends to to shown inFigs. 2

provide parallel arms 2, rounded at their outer extremities 3. Theblanlr as thus formed is then pressed at one operation to the form to 5,inclusive. The body form in cross-section and is deflected upwardportion 4 of the blank is bent to invertedU at the points 5, and thearms 2 are brought into'vertical parallel relation with ings 6 of eachpair of arms registering, as

7 shown. This prrssingof the blank provides a body portion of greatstrength and'rigidity and projects the ends and perforated arms upwardto facilitate their attachment to the elementsto which they are to besecured. v

the open- The construction of the complete device requires .only' twoopcrations-viz., the stamping out of the blankand'tlie pressing ofthesamc to completed form.

In Fig. 6 I have shown a transverse tion of a slightly-modifiedconstruction, in which the side walls latter being pressed into theparallel relation shown in Fig. 5 are pressed inward toward each other,which form maybe preferred for certain purposes.

This modification will involve an additional step or operation in theprocess of manufacture; but such further operation will add to'thecompactness and finished appearance of the connection.

What I'claimpand desire tosecure by Letters Patent, is-

I 1'. A pressed-steel connection comprisin a blank formed at its endswith longitudinal slots and having its body portion pressed toinverted-U shape in cross-sectionv 2. A ressed-steel connectioncomprising a fiat bl ank longitudinally slotted and perforated at itsends, and pressed to provide a body portion of inverted-U shape incrosssection, and parallel upwardly-directd arms.

3. A pressed-steel connection comprising a body portionof inverted-Ushape in crosssection having its ends upwardly inclined, and providedwith parallel perforated arms.

4. A pressed-steel connection comprising a blank longitudinally slottedat its ends and rounded and perforated, and having the body portionpressed into inverted-U shape. in cross-section, and provided withverticallyf disposed perforated arms.

5'. A -pressed-steel connection comprising a blankslotted and perforatedat its ends and pressed to provide a body portion the side walls ofwhich are deflected toward each other, and to bring the perforated endsinto vertical parallel relation.

In testimony whereof I affix my signature in the presence of twoWitnesses.
